Leak Detection in Arizona
Plumbers find hidden leaks by isolating sections of plumbing and testing them, then pinpointing the spot with acoustic listening, thermal imaging and moisture meters — so only a small, targeted opening is needed for the repair.

What drives leak detection calls in Arizona
Slab leaks
When: Heat cycling and shifting desert soils under slabs. What fails: Copper lines under the slab develop pinhole leaks. What to do: If you hear running water with everything off, ask for electronic leak detection before anyone breaks the slab.
Summer: Water heaters in hot garages and attics work under heat stress, and slab leaks show up as warm spots on floors or unexplained water bills.
Monsoon: Sudden downpours from July through September overwhelm yard drains and can expose roof and drain problems that stay hidden the rest of the year.
Most Phoenix and Tucson homes sit on concrete slabs, so supply lines often run under the floor or through the attic. Many homes from the 1970s through the 1990s have copper under the slab, and some from that period were built with polybutylene supply lines, which are now commonly replaced.

How do I test for a hidden leak?
Turn off every fixture and appliance, note the meter, and check again after 30 minutes without using water. If it moved, there's a leak. Close the house shutoff and check again; if it still moves, the leak is on the service line.
